  • Made a Great Gift
Pattern Name: Megohmmeter
My son, who is an air conditioning tech, wanted this for Christmas so I got it for him and he reported back to me that he wished he had one earlier because he used it to show customers the results on the meter and he sold two units that he might not have sold otherwise. He is very scrupulous to not try to sell customers new units unless they are needed and customers are wary of techs trying to sell them units before they are needed. He felt very secure in telling the customers that they would soon need a new unit based on the meter's readings. It served as an honest and effective sales tool which also saved the homeowners problems of a future breakdown. He profusely thanked me for this gift. ... show more

  • Wasn't sure the size of the battery
Pattern Name: Megohmmeter
I had to tried different batteries to find out which one actually fits, since it didn't came with instruction for the battery type or how to operate. But my co-worker suggested it.

  • Cheap, reliable and simple. Love it.
Pattern Name: Megohmmeter
I've been using these at work and love them. Light weight, simple to use and reliable. This will not get down to the finer details of measuring resistance readings but will tell you where the weak spots are in a circuit. The lower cutoff point on this meter's scale is 20 Megaohms, well above levels I have seen circuits operating without tripping overloads or breakers. All of the problem circuits I've diagnosed with my expensive Fluke megger have shown less than 1 Megaohm from conductor to ground. I still love this meter, though, because it is so light and compact. I also like that I can attach the alligator clips and leave one hand free to wiggle wires in the conduit on intermittent problems while I press the test button with the other. I have thus far not misdiagnosed a motor with this meter but I usually go get my Fluke 1507 if I am in doubt. You will love this megger. ... show more
